T 0 all whom i! may conccrn:

Be it. known that 1, Roman l5. Cocnnwx, a citizcn of thc United States, I'Qsttlthg' at Charlotte, in the county of Mccklonliurg and State of North Carolina. have inventcd a new and u clul Machine for Making llottlc-Caps, of which thc following is a specilication. r.

This invention has rcl'crcncc to improvelncnts in machines for making bottle caps and has a special rcl'ercnce to the machine for the same pnrposc hown and dei crihed in application Scrial No. 457,373, tiled by inc on October 12, 1908.

The ohject of the prcrcnt invention is to improve the construction of the machine (liscloscd in the fin-maid application in several particnlais and also to providc a means whet-eh any choscn dcrignation may he pr0- duced upon thc outer or visible face of the bottle cap or crown by the machine during the operation of forming the cap or crown.

The invention will be best understood from a consideration of the follow ng detail dCSCl'il)li()ll taken in connect ion with the accompanyin drawings forming a part of this specification in which drawings, Figure 1 is a plan. view with parts lLJOken away of the improvtal machine. Fig. .3 is an cnd elevation of a portion of thc machine also with parts broken away and parts omitted. Fig. 3 is a detail elevation with parts in .-cction of the inking apparatus. Fig. 4 is a detail clevat ion with parts in sectiuu of the means for feeding the metal strips out of which the bottle caps or crowns are punched.

in thc aforesaid application, in thc structure disclosed, of which the present invention i an impri'ivcmcnt. thcrc is shown a die plate capable of rotative movement and containing a circular .-'t!'it.- of dics.

In operative relation to thc die plate are a number of plungcwarranged in consecutivc ordcr. the. first in order hein; adapted to court with the dies in thc dic platc to j punch ut blanks from a strip of metal and shape t-licsc hlanlw into b ttle caps or crowns. then thc ncxt (he in order applic a ccmcnt to the interior of thc .-hapcd cap or crown.

and finally cork tll 'l\'.\' are moved into o.-'ltion ovcr the shaped and c un-ntcd crown and these cork risk are forced into tho crowns by the third plunger, the several pluugcrs acting simultaneously suitahlc actuating mechanism.

Provision was made in the structure of thc aforesaid application for causing the actuation of thc plungers and also the step by step rotativo movement of the die cart'ltl. Y

The prcacnt invention has rcfcrence more particularly to the means for giving the st'cp h a tcp rotative moremcnt to the die carricr and to added features over and ahme the showing of he aforesaid application including: a moans for feeding the metal strips and for applying ink to the dies previous to the punching out of the caps from the metal strips.

ltct'crrin; now to thc drawings thcrc is hown a diii carrier 1 having upon its upper facc a circular Ferica of (lit-5 :3 which lat termay he in all essential rcspects similar to thc dic J hown in thc at'orcsaid application.

llxtcnding through thc axis of the disk through upper end of this post or tcm thcrc iS a head 4 receiving and actuatin 1 thrcc lovers .3, t 7, at one end, thc said lcrcrs lieing pivoted at tho other end in thc standards S.

The levers 5, t3, 7 carry t(,. 'pccli\tl a punching die, a cciucut supplying head or plungcr, and a plunger for causing the insert ion of the cork dislt's into the cemented crowns or caps. The #tcms i) only of these thrce plunger-s arc shown cxct-pf that in Fig.

l)l:llll{s from a metal strip is indicated.

In the aforesaid application provision is made for causing a longitudinal rcciprocation of the stem 3 through a frame 11 within the casing 12 of the machine, and a cam 13 carricd on a Shaft l t and arrangcd to engage thc frame ll to dcprcss the same against a normal upward tendency impartcd to thc frame by nitahlc prings, fully illustrated in the afoicsaid application butnot r-lltm'tt in thcprcscnt case. Bvthismeans the stem 3 is given a positive downward movement at suitable intcrvals and is alf lowed to rcturn to normal position through thc action of the prings. the downward movcmcnt being the only one rctpiiring power.

In the structure illustrated in the presentapplication the shaft Ll cxtcrior to the easing 1 carries a gear wheel 15 in mesh with thc punching head 10 for cutting out the is a post or tem it, (are Fig. 3.) and at the a gear pinion 16 on a shaft 17 receiving power through a pulley 18 from any suity the same vertiea able source of power so that the shaft 14 is caused to rotate continuously so long as the power is appliedt.

Tie peri hery of the disk 1 is in the structure siow'n in the presentdrawings provided with bevel gcarteeth 19 extendima entirely around the die carrier disk 1 an these gear teeth are in mesh with a bevel pinion 200m a shaft 2/1 suitably supported in bearings 22 carried-by the casing 12 and this shaft extends radially over the disk 1 and at a short distance above the same. The support or-bearing 22 may also carry an overhanging bracket 23 extending to the inner end of the shaft 21 and there sustaining the latter. On the shaft 21 near the axis of the disk 1 is a roller '24 and immediately below the same is a small idler roller 25.

Mounted in the post 8 carrying the lever is another shaft 26 carrying a roller 27 with an adjacent idler 28. The rollers 24 and 27 and the unching die are all in l plane so that a strip of metal fed between the rollers 24 and 25 and -continuing through the rollers 27 and 28 .will pass under the punch 10 immediately above any one of the dies 2 which at the moment is beneath the punch 10, the arrangement being such that the step by step rotation of the dislrl will alwa s bring the dies 2 in succession at rest eneath the punch 10.

The shafts 21 and 26 are parallel one with the other although in spaced relation and the shaft 21 carries a sprocket Wheel 29 while the shaft 26 carries a corresponding sprocket wheel 30 and the sprocket 'wheels are of the same diameter and are connected by a sprocket chain 31 so that the shafts 21 and 26 will'rotate simultaneously at the same speed.

Since the pinion 20 on the shaft 21 isin constant mesh with the gear teeth 19 on -the disk 1 the feeding rollers 24 and 27 are punched will occur only during the will have the same intermittent movement as does the disk 1 so that the feed of the strip from which the cap or crown blanks movement of the die 1 and when the ttei' comes to rest the strip will also be at rest,

1 after which time the punch 10 acts to punch out a disk from the strip and subsequently form it into a bottle cap or crown in the manner described; in the aforesaid application.

The means for imparting step by step rotative movement to the disk 1 is quite different from that shown in the aforesaid application. The periphery of the disk 1 below the gear teeth 19 is provided at spaced intervals corresponding to the spaces between the dies 2 with inclined notches 32,

Pivotcd at one side of the casing 12 is arock arm 33 at one end of which there is a stud 34 with a pointed end 35 adapted to enter anyone of the notches 32 in such manner as to hold the disk 1 against rotation except when a sulliciently powerful rotative force is exerted upon the disk 1 to cause the pointed end 35 to ride out of a notch 32 in which it may at the time he in engagement. The end of the arm 33 remote from the min 34 is controlled by a spring 36 tending at all times to maintain the pin 34 in a notch 32'.

Mounted on the shaft 14 is bevel pinion 37 'in mesh withanother bevel pinion 38 on a shaft 39 extending to the exterior of the casing 12 and there carrying a bevel pinion 40 in turn in esh with a bevel pinion 41 on an upright shaft carried by. suitable journal bearings 43 fast on the d'asing 12. The upper end of the shaft 42 carries a disk 44 an on this disk is ivoted a pawl 40, having at the other end a tooth 47. A pin 48 rising from the disk 44 constitutes the pivot of the pawl 45 and connected to this pin is one end of a bar 46, the other end of which is slidable through a recess in the upper face of a head 46' pivotally mounted in a stud 46" on the casing 12. The toothed end 47 of the pawl 45 is arranged to engage constantly the. eriphery of the disk 1 at a oint to engage t e notches 32, the said paw being constantly urged in a direction to move into the notchcs 32 by a spring 40 connected at one end to the pawl and at the other end to the rod 46. As the disk 44 rotates the pawl 45 will have its toothed end 4'? reciprocate along the periphery of the disk 1 for a distance sufficient to engage a notch 32 and rotate the disk to advance the dies step by step. A pin 50 on the casing 12 acts as a stop for the pawl in its retractlve movement.

Fast on the stem 3 and projecting laterally therefrom is an arm 51 to the outer end of which is secured a depending sleeve 52 through which extends a rod 53 having at its lower end a head 54 rovided on the lower face with a pad 55. etween the head 54 and the sleeve 52 the rod 53 is surrounded by a spring 56 tending to force the head 54 in a direction away from the sleeve but this movement is limited by a nut 57 applied to the rod above the arm 51 or by any other suitable limiting means. 1

Extending longitudinally through the rod 3 53 is a passage 58 leading to the pad- 55 on the head 34 and at the oth r end onnnn nicatita: with the re.-' rvoir arried by the uhtier and it the rod J13. t
